- Magnetic Resonance Imaging A) No hyperintensity on T2-weighted sagittal image, B) No hyperintensity on t2-weighted axial images, C) Central Hyperintensity on a T2-weighted sagittal image at the T5 vertebra level is consistent with myelitis, D) T2-weighted signal increase on axial image at the same level.

- Magnetic Resonance Imaging A) T2 Weighted signal increase along with central cystic necrotic changes on T7–8–9 vertebral levels. Also note that posterior adhesion of spinal cord is raising suspicion for postoperative arachnoiditis, B) Similar findings on T2-weighted axial image at the T8 vertebra level, C) Long-segment hyperintensity on a T2-weighted sagittal image at the T9–L1 vertebra levels is consistent with myelitis D) Hyperintensity on a T2-weighted axial image at the T10 vertebra level.
